Preparing for Cleaning Outdoor Decorative Stones

Before you begin cleaning your outdoor decorative stones, it’s important to take some preparatory steps to ensure effective and safe cleaning:

Clear the Area

Remove any objects or furniture placed on or near the decorative stones. This will give you unobstructed access to the entire surface and prevent any accidental damage to surrounding items.

Sweep or Brush Away Loose Debris

Using a broom or a brush, gently sweep or brush away any loose dirt, leaves, or debris from the surface of the stones. This step will make the subsequent cleaning process more effective.

Test a Small Area

Before applying any cleaning solution to the entire surface, it’s advisable to test it on a small, inconspicuous area of the stones. This will help ensure that the solution does not cause any unwanted discoloration or damage to the stones.

Cleaning Techniques for Outdoor Decorative Stones

Now that you’ve prepared the area, it’s time to clean the outdoor decorative stones. Here are some effective cleaning techniques you can use:

Water and Mild Soap Solution

For routine cleaning, a mixture of water and mild soap can be highly effective. Fill a bucket with warm water and add a few drops of mild dish soap. Stir the solution gently to create a soapy mixture. Dip a soft-bristle brush or a sponge into the solution and scrub the stones in a circular motion. Rinse the stones thoroughly with clean water.

Vinegar and Water Solution

Vinegar is a natural and effective cleaning agent that can remove stains and disinfect outdoor decorative stones. Mix equal parts of white vinegar and water in a spray bottle. Spray the solution onto the stones and let it sit for a few minutes. Scrub the surface with a brush or a sponge, paying extra attention to stained or heavily soiled areas. Rinse the stones with water to remove any residue.

Pressure Washing

If your outdoor decorative stones have stubborn stains or accumulated grime, you may consider using a pressure washer. Ensure that you read and follow the manufacturer’s instructions for operating the pressure washer safely. Use a low-pressure setting and hold the nozzle at a distance to avoid damaging the stones. Move the nozzle in a sweeping motion, covering the entire surface of the stones. Be cautious not to concentrate the water stream on one spot for too long, as it may cause erosion or damage.

Bleach Solution

For tough stains or mildew growth on outdoor decorative stones, a bleach solution can be effective. Mix one part household bleach with three parts water in a bucket. Apply the solution to the stained areas using a sponge or a brush. Let it sit for a few minutes, then scrub the surface gently. Rinse the stones thoroughly with water to remove any bleach residue.

Commercial Stone Cleaner

If you prefer using a specialized cleaner, there are various commercial stone cleaners available in the market specifically formulated for outdoor use. Follow the instructions on the product label for the recommended dilution ratio and application method. Apply the cleaner to the stones, scrub if necessary, and rinse thoroughly.

Maintaining Outdoor Decorative Stones

Once you have successfully cleaned your outdoor decorative stones, it’s important to maintain their appearance and longevity. Here are some tips to keep in mind:

Regular Cleaning

Perform routine cleaning of the decorative stones to prevent dirt, debris, and stains from accumulating. Regular sweeping or brushing, along with occasional washing with a mild soap solution, will help maintain their appearance.


Consider applying a stone sealer to protect the surface of the decorative stones from stains and moisture penetration. Check with a local stone supplier or home improvement store for suitable sealers for outdoor use. Follow the manufacturer’s instructions for application and reapplication.

Avoid Harsh Chemicals and Abrasive Tools

To prevent damage to the stones, avoid using harsh chemicals, bleach, or abrasive tools that can scratch or erode the surface. Stick to gentle cleaning solutions and soft-bristle brushes or sponges.

Regular Inspections

Periodically inspect the outdoor decorative stones for any signs of damage, cracking, or loose pieces. Address any issues promptly to prevent further deterioration.

Professional Cleaning

For extensive stains, deeply embedded dirt, or delicate stone surfaces, it may be advisable to seek professional cleaning services. Professionals have the expertise and specialized equipment to handle the cleaning process effectively and safely.
